Matthew 27:44: Even the robbers who were crucified with Him reviled Him with the same thing.

Luke 23:39-42: Then one of the criminals who were hanged blasphemed Him, saying, “If You are the Christ, save Yourself and us.” But the other, answering, rebuked him, saying, “Do you not even fear God, seeing you are under the same condemnation? And we indeed justly, for we receive the due reward of our deeds; but this Man has done nothing wrong.” Then he said to Jesus, “Lord, remember me when You come into Your kingdom.”

Matthew says that both of the robbers mocked Jesus, but Luke says that only one of the robbers mocked Jesus.
